Method of inspecting disc information

Abstract

A method of inspecting disc information stored on an optical disc, for applying in an optical drive of a computer system. The method of inspecting disc information comprises a. outputting a standard command, for reading the disc structure of the disc; b. determining whether the reading was successful, if not, step c is performed; if yes, step d is performed; c. outputting a force read command, for reading the disc structure; d. receiving the disc structure; and e. outputting the corresponding disc information according to the disc structure. The invention can inspect various disc information of the optical disc, and the user database can be manually updated and expanded according to a user's will, thereby increasing the convenience of inspecting optical discs.

1 . A method of inspecting disc information stored on an optical disc, for applying in an optical disc drive of a computer system, the method comprising: 
 a. outputting a standard command, for reading the disc structure of the optical disc;    b. determining if the reading is successful, if not, performing step c; if so, performing step d;    c. outputting a force read command, for forcefully reading the disc structure of the optical disc;    d. receiving the disc structure of the optical disc; and    e. outputting correspondingly the disc information according to the disc structure of the optical disc.    
   
   
       2 . The method according to  claim 1 , wherein the disc structure is being searched for in a user database during step e, and the corresponding disc information is outputted if the search in the user database is successful.  
   
   
       3 . The method according to  claim 2 , wherein the user database is being created by a user.  
   
   
       4 . The method according to  claim 2 , wherein the disc structure is being searched for in a program database if the disc structure search in the user database is unsuccessful during step e, and the corresponding disc information is outputted if the search in the program database is successful.  
   
   
       5 . The method according to  claim 2 , wherein the program database is embedded in the optical disc drive.  
   
   
       6 . The method according to  claim 4 , wherein the disc structure is being searched for in a built-in database if the disc structure search in the program database is unsuccessful during step e, and the corresponding disc information is outputted if the search in the built-in database is successful.  
   
   
       7 . The method according to  claim 6 , wherein the built-in database is embedded in the optical disc drive.  
   
   
       8 . The method according to  claim 1 , wherein the disc structure comprises at least one of a disc manufacture code, a dye type code, a media type code, a nominal capacity code, and a recording speed code.  
   
   
       9 . The method according to  claim 8 , wherein the disc information corresponds to the disc structure, the disc information comprising at least one of a disc manufacture name, a dye type, a media type, a nominal capacity, and a recording speed.  
   
   
       10 . The method according to  claim 1 , wherein the optical disc is a CD-R or a CD-RW recordable optical disc.  
   
   
       11 . The method according to  claim 1 , wherein the optical disc is a DVD-R or a DVD-RW recordable optical disc.  
   
   
       12 . The method according to  claim 1 , wherein the optical disc is a DVD+R or a DVD+RW recordable optical disc.
